we have single domain and recently we purchased three companies, My job was to handel Security side and other Admin was handling AD.... now he left and i have to resolve all issues..i do have Manging AD Network but i would be greatful if a expert can share his experience with me.
we will have totally 100 offices, 2500n users, as off now the companies have very poor IT Team + Infrasturcutre. i was planning to keep our doamin and add child doamin or simply add rodc on all the office.... i have made a chart like this
branch users less then 7------------NO DC/NO RODC (Authentication via VPN)
branch users less then 15-25------RODC
branch users less the 25 above---DC
we will be using Sonicwall as a Secuirt Device + Symantec Endpoit Suit 4.0...
All the application serevr will be @ HO, we will have two Applications.
how many subents should i make?
Shall i keep single domain or make child doamin where users are more?
i am planning to have exch 2010 on win 2008 ENT.
